This is a very important book on a topic that I've been thinking a lot about recently. There is a hidden societal cost on our population's obsession with smartphones and social media, that is not talked about and poorly understood. This book explores behavioural addiction, how it compares to previous addictions (like substance addiction) and what causes it. There's a good mix of research and anecdotes in this book, and the book is very easy to devour in a couple days.

I think there's going to be a lot more discussion in the next couple years about the mass addiction to likes and shares, and this book prepares you fairly well on the subject. I'll be exploring it more, and hoping to create systems or apps to make sure I don't get sucked into the hole of social media/video games/VR/whatever people come up with next.
